Mail Merge Help

I am trying to use mail merge to allow me to use a list of data in excel (Column A would be equal to a header row, Column B is the actual data i want output to my word doc.) the goal is when i get a new insurance claim, i could use excel to input data then mail merge would put the data in my word document which i use to copy into our claims management system. Currently, when I receive a new claim i have to manually type out my word document answers (i can copy & paste once the info is in word) but the whole process takes 30-45 mins per claim. If i can make the system more autonomous, then i can reduce my time spent per claim down to 5-10 mins. once the mail merge is complete, i will save the word doc as a new document and i can input new information into the excel doc.

Photos below. Thank you in advance for your help. some information had to be redacted for security reasons.
